INA housing units are available as pedestal bearings, flange bearings, and clamp housing units in a wide variety of designs. The units are ready for assembly and consist of INA grey cast iron or INA sheet steel housings with integrated INA clamp bearings. Cast housings are single-piece and can withstand high loads. Sheet steel housings are two-piece and are used when the focus is not on the load capacity of the housing but on a low unit weight.
To ensure functionality and safety under all operating conditions, bearings and housings are matched to each other.
The spherical outer surface of the bearing outer ring and the hollow spherical housing bore compensate for static shaft misalignment in housing units.
The units are primarily used as fixed bearings, but at low loads and speeds, they are also suitable as floating bearings. The housings are bolted to the mounting structure.
Pedestal bearing units have either a long or short foot. Housings with a long foot are bolted to the mounting structure via elongated holes, whereas housings with a short foot are fastened by blind threaded holes.
Flange bearing units are supplied as two-hole, three-hole, and four-hole units. The housing shapes are oval, triangular, square, or round. The housings have through holes for mounting. Some series are also available with a centering collar. The centering collar is mounted in a recess in the machine wall, precisely aligning the housings and relieving the mounting bolts from occurring radial forces.
Clamp housing units are either adjustable or pivotable. They are used when shafts require long axial adjustment travel.
